ANTIFUNGAL COMPOSITION Prevention of mould growth is an important topic to the food industry. Fungal spoilage can lead to considerable economic losses. Further, some mould species that contaminate food products, such as cheese, can produce mycotoxins which can penetrate into the food product (Scott, "Mycotoxigenetic fungal contaminants of cheese and other dairy products" Mycotoxins* in dairy products, Elsevier Science Publishers LTD, 193-259 (1989)) Therefore, removal of visible mould from a food product gives no guarantee of safety to the consumer.
15 For more than 30 years natamycin has been used to prevent fungal growth on cheeses and sausages.
Natamycin can be added to an emulsion of a polymer in water, mostly polyvinyl acetate, which is applied as a cheese coating (Daamen, C.B.G. and Berg, G van den; "Prevention of mould growth on cheese by means of natamycin" Voedingsmiddelentechnologie, 18 26-29 (1985)). Cheeses can also be treated by immersion in a suspension of natamycin in water (Morris, H.A. and Castberg, "Control of surface growth on blue cheese using 25 pimaricin" Cultured Dairy Products Journal, 15 21-23 (1980)). Sausages, however, are mainly treated by immersion or by spraying with a suspension of natamycin in water (Holley, "Prevention of surface mold growth on Italian dry sausage by natamycin and potassium sorbate" Applied and Environmental Microbiology, 41 422-429 (1981)).
Usually polymer emulsions for coating purposes contain 0.01 to 0.05% of natamycin, while aqueous suspensions for immersion treatments contain 0.1 to 0.2% of natamycin.
These treatments are generally effective in preventing fungal spoilage. However, fungal spoilage of products such as cheeses and sausages treated by dipping or spraying with an aqueous suspension of natamycin can still occur (Holley 2 cited previously and Moerman, -"Schimmelwering op vleeswaren door Pimaricine" Voedingsmiddelentechnologie, 3 (51/51), 261-64 (1972)). This may be caused by an inhomogeneous distribution of natamycin on the surface of the product.
Holley describes the use of the thickening agent hydroxypropylmethylcellulose (HPMC) to prevent drip-loss of sorbate and natamycin from salami surfaces. It was demonstrated that drip-loss was reduced when HPMC was used at a concentration of However HPMC is not a suitable thickening agent for use in spray coating or dipping methods using aqueous suspension because of the long drying time.
Although dripping can be prevented using concentrations of HPMC of 1% or more, the drying time of a product treated 15 with a composition comprising 1% or more of HPMC will be more than 2 days. This is unacceptable for most practical purposes as the products e.g. cheeses or sausages can not be handled transported) before they are dry. Lower concentrations of HPMC 1 or 2 g/l) produce no 20 substantial increase in the amount of natamycin on the treated surface. The term dry used herein means "hand-dry" i.e. dry enough for the products to be handled without undue Sdifficulty.
S DESCRIPTION OF THE INVENTION The present inventors have found that a product treated with an aqueous composition comprising one or more suitable thickening agents in general in concentrations of 1 *to 5 g/l, preferably 1 to 3 g/l, by dipping or spraying was dry within 5 hours. A drying time of 5 hours is acceptable for cheese and comparable with the drying time when dipping or spraying suspensions are used which do not contain a as thickening agent.
The present invention relates to improved compositions of polyene fungicides, such as natamycin, which are suitable for the surface treatment of products especially natural products and particularly food products such as cheeses and 3 sausages. These compositions may be used in a variety of applications including treatment of products by dipping and spraying.
Unexpectedly it has been found that mould growth on s the surface of products is markedly reduced when they are treated with a composition wherein a suitable thickening agent is added to the aqueous dipping or spraying suspensions of polyene antifungal agents. Preferred compositions when applied to the product to be preserved, are capable of being dry at 20 0 C within 5 hours at a relative humidity of 80%. The compositions also preferably give rise to an increase in the amount of natamycin on the surface of the product to be preserved of at least preferably at least 100%, when compared with the amount of is natamycin present on the surface of the product in the case where a composition not comprising the suitable thickening agent is used.
The present inventors have found that the insufficient protection against fungal growth following 20o dipping or spraying treatment with an aqueous suspension of a polyene antibiotic may be caused by the fat content of the product to be treated. The distribution of polyene fungicides, such as natamycin on surfaces containing a high amount of fat has been found to be inhomogeneous. The inhomogeneous distribution of the polyene fungicide is the consequence of the presence of fat particles at the surface Sof the products. When natamycin is added to the product via for example a coating, such as polyvinyl acetate, the distribution of the polyene fungicide will normally be homogeneous enough to prevent fungal infection. However, when products, for example cheeses or sausages, are treated by spraying or dipping methods using an aqueous composition, this will not always be the case. We have surprisingly found that the inclusion of the suitable thickening agent in the polyene antifungal composition leads to an increase in the degree of homogeneousness of the distribution of the polyene antifungal compound over the surface of the product. Also, the adhesion and the amount of natamycin to the surface of the food product is improved.
4 An improvement in the adhesion of the polyene fungicide may be of interest in the case of pre-soaking of casings used in the production of sausages. The pre-soaking of casings, which are generally protein-based or celluloses based casings, in a conventional composition of natamycin is not a generally effective method of preventing fungal growth on the sausages (Holley Moerman). The absorption of natamycin into the casings may not be optimal. Also, after coating of the sausages with the casing the sausages are usually washed by spraying with water. During this washing step part of the natamycin is washed from the sausages.
According to one aspect the invention provides an antifungal composition comprising one or more polyene antifungal compounds, one or more thickening agents whereby none of the thickening agents is hydroxypropylmethyl cellulose (HPMC) and a salt selected from the group consisting of sodium chloride or potassium chloride.
Preferably the dry composition is an anhydrous composition most preferably a powder In a further aspect the invention provides an aqueous composition which may be a suspension. The aqueous composition may be prepared by dissolving the powder composition in a sufficient amount of water or by adding the polyene fungicide and the thickening agent separately. T h e invention also provides the use of the anti.fungal compositions of the invention for the treatment of natural products in particular food products such as cheeses and sausages including the pre-treatment of coatings such as casings for sausages and agricultural products such as fruit, grain, seed-potato, vegetables, flower bulbs, seed or feed products. The invention also provides the use of the compositions in pharmaceutical applications, in particular for applications which involve topical use of the composition. Examples of suitable pharmaceutical preparations are lotions, creams, ointments and shampoos.
The polyene antifungal compounds used in the compositions of the invention are preferably one or more of natamycin, nystatin, lucensomycin or amphotericin B. The preferred polyene compound is natamycin. In the preparation of compositions of the invention, one or more polyene Santifungal compounds may be used or pre-prepared 5 compositions containing such antifungal' components may be used. An example of such a preparation is the commercially available- powder composition sold under the trade mark Delvocid® which contains 50% natamycin.
The concentration of polyene fungicide in the aqueous suspension will generally be from 0.1 to 20 g/l, more preferably from 0.5 to 8 g/l and most preferably from 1 to g/l.
In compositions of the invention the preferred thickening agents include all thickening agents known in the art for use in food products except HPMC, preferably the thickening agents are gums, more preferably xanthan gum and/or gellan gum.
The one or more thickening agents in the aqueous 15 composition are preferably present in an amount of 0.5 to g/l, more preferably from 0.5 to 20 g/l and most preferably from 1 to 3 g/l.
In a preferred embodiment the composition of the invention further comprises a salt, preferably a metal 20 halide salt e.g. sodium chloride or potassium chloride.
Sodium chloride is most preferred as salt. The salt is preferably present in an amount of 10 250 g/l, more preferably 50 200 g/l, most preferably 50 100 g/l. When the composition is aqueous the salt improves the drying properties of the composition on the product. Salt also prevents bacterial growth in the aqueous composition allowing it to be stored for a moderate time period. To prevent bacterial growth also any antibacterial agent which is known in the art may be included in the composition.
A suspending agent may be included in the composition. The suspending agent serves as a deflocculant.
Suitable suspending agents are for example microcrystalline cellulose-sodium, carboxymethylcellulose (Avicel® RC), sodium dodecyl sulphate, polyethylene glycol, fumed silica, glycol and glycerol.
In some embodiments it has been found that no buffer is needed for the suspension. In general the pH of the suspension will be between 3 10, preferably the pH will be 6 between 6 9, more preferably between 6.2 8.5 for the optimal natamycin addition and drying time.
An additional advantage of an aqueous suspension according to the invention is that the suspension is physically stable for at least 10 days without stirring.

The invention will now be described by way of example with reference to the accompanying Examples which should be regarded as non-limiting.
Example 1 A dipping bath was made up using 5 g Delvocid® 1 together with 80 g sodium chloride 1 and several concentrations of xanthan gum (Keltrol® RD, Kelco International Limited) in the order from 1 to 4 g/l Cheese blocks of young Gouda cheese (Fat content more than having dimensions 3*3*3 cm, were dipped in the solutions.
A minimum of 10 cheese blocks per trial were tested. The 1i weight increase after dipping and the homogeneous distribution of the dipping solution on the block's were measured.
The dipping solution gave a linear increase in adhesion based on the concentration of xanthan gum from 2 3 mg 20 natamycin dm 2 to more than 10 15 mg natamycin dm 2 (Figure 1).
Example 2 A dipping bath was made up using 5 g Delvocid® 1 together with 0 or 4 g/1 of xanthan gum (Keltrol® RD, Kelco International Limited).
Italico cheeses, cylinder type cheeses having an area of 11.3 dm 2 and a weight of 1.8 kg, were dipped in the described suspensions and the amount of dipping solution used was measured after dipping 10 cheeses.
The initial concentration of natamycin on the cheese was respectively 3 and 10.3 mg/ dm 2 also shown in Figure 2.
Example 3 A dipping bath was made up using 5 g Delvocid® 1 together with 0, 2 and 4 g/l of xanthan gum (Keltrol® RD, Kelco International Limited).
Casera cheeses, cylinder type cheeses having an area of 30.8 dm 2 and a weight of 8 kg, 8 were dipped in the described suspensions and the amount of used dipping solution is measured after dipping 10 cheeses.
The initial concentration of natamycin on the cheese was respectively 2.8, 8.8 and 12.7 mg/ dm 2 (Figure 2).
Example 4 A dipping bath was made up using 5 g Delvocid® 1 together with several concentrations of xanthan and 0 and 80 g/l sodium-chloride.
Gouda cheeses directly, after brining, were cut into blocks of dimensions 10*10*7 cm and dipped in the described dipping suspensions.
The blocks were incubated at a relative humidity of 81 and a temperature of 6 0
C.
15 The used salt has no influence on the amount of natamycin adhered to cheese surface (Figure 3).
Salt has a great influence on the drying behaviour of the Sdipped cheese blocks.
Using high concentration of xanthan than 3 g/l) or use a 20 dipping solution without salt gives an unacceptable drying time of the cheese (more than two days).
The results are listed in detail in table 1.
